ruanjinjie ce1b3a41e7 of: overlay: fix null pointer dereferencing in find_dup_cset_node_entry() and find_dup_cset_prop() 
[ Upstream commit ee9d7a0e75 ]

When kmalloc() fail to allocate memory in kasprintf(), fn_1 or fn_2 will
be NULL, and strcmp() will cause null pointer dereference.

Fixes: 2fe0e8769d ("of: overlay: check prevents multiple fragments touching same property")
